SLIDING DOOR-PULL.

SPECIFICATION forming part of Letters Patent No. 287,039, dated October23, 1883.

Application filed July 25. 1883. (ModeL) To all whom it mag/concern.-

Be it known that I, TrroMAs LYoNs, a citizen of the United States,residing at Hartford, in

the county of Hartford and State of Connectiout, have invented certainnew and useful Improvements in Sliding Door-Pulls,of which the followingis a specification.

My invention relates to improvements in sliding door-pulls; and theobjects of my invention are to so arrange the push-pin and itsconnecting-lever as to throw the handle out of the door to the fullextent of its movement; also, to have the throwing-lever engage the pulland hold it in position when it is either wholly without or whollywithin the case. I attain these objects by the simple constructionillustrated in the accompanying drawings, in which Figure l is a sideelevation of my pull, with the cap of the case removed. Fig. 2 is a likeview'of the same, with the pull thrown outward, and with one position ofthe throwinglever indicated by broken lines. Fig. 3 is a view lookingupon the face-plate of my pull, and Fig. 4 is a horizontal section ofthe case on line as x of Fig. l, with the other parts in elevation aslooking upward from below. The case may be of any ordinary construction.I

A designates the pull proper, the inner end or shank, a, of which restsbetween suitable guides on the case, and its lower edge is pro videdwith two holding-notches, b and p. The throwing-lever B is pivoted tothe case at d, and to the push-rod C at e. A spiral spring, f, with oneend resting against the side of the case and its other end against theend of the push-rod, acts with a constant tendency to hold the push-rodand the throwing-lever in the positions shown in the drawings. When thepull is wholly within the case, as shown in Fig. 1, the arm 9 of thethrowing-lever enters the hooked notch Z) on the shank of the pull andpositively locks the pull against an outward movement until said leveris withdrawn. By depressing the end of the pushrod the arm 9 iswithdrawn from the hooked notch b, and immediately thereafter the arm hof the throwing-lever engages the rear end of the shank of thepull.Byaoontinued movement of the push-rod the pull A is thrown into theposition indicated in Fig. 2, and the lever B is thrown into thatposition which is indicated by broken lines in said figure. Uponreleasing'the push-rod the spring throws the rod and the throwing-leverback again, when the hooked arm enters the curved recess 0 in theunder'sideof the shank of the pull, and holds the same in its extendedposition.

recess is not very abrupt, so that the arm 9 can be disengaged from thenotch by sufficient pressure upon the outer end of the pull. Byreferring to the two positions of thethrowing-lever, as shown in Fig. 2,it'will be seen that it has sufficient throw to carry the pull outwardto its full extent. The pull is prevented from being thrown or Jdrawnwholly from the case by means of a stop-lug on the case between the twoguide-lugs, as indicated by the transverse broken lines in Figs. 1 and2. The shank of the pull is made thin for the greater portion of itslength, and the flat side of said thin portion rests upon said stop-lug.The end of the shank is thickened to form a shoulder, as indicated bythe transverse broken The engaging surface of the hook and thisrounded 1. The combination of a sliding pull, the

throwing-lever pivoted to the case at d, and having the arm h, whichengages the rear end of the shank of the pull and throws the pulloutward, the push-rod pivoted to the short end of the throwing-lever,and the spring which acts upon the push-rod to force it outward,

substantially as described, and for the purpose specified. K p

2. The combination of the pull having a holding-notch, b, in the lowerend of its shank, the spring-pressed throwing'lever having the arm 9,which engages said holding-notch, and the arm h, which engages the rearend of the shank of the pull, substantially as described, and for thepurpose specified.
